23 September 1989: City 5-1 United
City trounced a United side that was in transition.

David Oldfield grabbed two goals for the Blues and Trevor Morley, Ian Bishop and Andy Hinchcliffe also found the back of the net.

Reds boss Alex Ferguson, who walked off to chants of "Fergie out" from his side's fans, recalls: "By late September our form had been inconsistent and we chose the worst possible day to reach rock-bottom.

"We were slaughtered 5-1 at Maine Road in the most embarrassing defeat of my management career.

"After the game I went straight home, got into bed and put the pillow over my head."

18 November 2000: City 0-1 United
Newly-promoted City were undone by a brilliant David Beckham free-kick in the first Manchester derby for four-and-a-half years.

Beckham struck the winner after just 95 seconds of a tempestuous match and later said: "It was a big test for all the players and they kept their composure.

"I was very happy and it was nice to get another goal, but we did want to play a lot better than we did.

"We knew it was going to be hard and we knew we would get a little bit of stick."
